mescc: Update elf32-header for linux-4.17.
Previously, our binaries showed this

    $ readelf -s scaffold/main.mes-out
    There are 2 program headers, starting at offset 64

    Program Headers:
      Type           Offset   VirtAddr   PhysAddr   FileSiz MemSiz  Flg Align
      LOAD           0x000000 0x01000000 0x01000000 0x0557c 0x0557c RWE 0x1
      LOAD           0x000000 0x01000000 0x01000000 0x0557c 0x0557c RWE 0x1

     Section to Segment mapping:
      Segment Sections...
       00     .text .data
       01     .text .data

Linux-4.17 refuses to run this and says

    Uhuuh, elf segment at 0000000001000000 requested but the memory is mapped already
    Segmentation fault
